Privacy
Policy

Last updated: March 2026

Summary: IndexBody does not collect personal health data. All calculator results are computed in your browser and are never sent to our servers. We use Google Analytics for traffic analytics and Google AdSense for advertising, both of which may use cookies.
1. Who We Are

IndexBody (indexbody.com) provides free, evidence-based health calculators and educational articles. We are not a medical provider and do not collect health records or personally identifiable health information.

2. Data We Collect

Calculator inputs: Numbers you enter into our calculators (height, weight, age, etc.) are processed entirely in your browser using JavaScript. These values are never transmitted to our servers.

Saved results: If you use our Save Results feature, results are stored in your browser's localStorage. This data stays on your device and is not accessible to us.

Analytics data: We use Google Analytics 4 to collect anonymised information about how visitors use our site, including pages visited, time on site, device type, and geographic region. This data does not personally identify you.

Contact form submissions: If you contact us via the contact form, your name, email address, and message are processed to respond to your inquiry.

3. Cookies

IndexBody uses cookies from third-party services:

  • Google Analytics cookies — used to measure traffic and usage patterns. You can opt out via Google Analytics Opt-out.
  • Google AdSense cookies — used to serve relevant advertisements. Google may use cookies to personalise ads based on your browsing history.
  • localStorage — used to store your saved calculator results locally in your browser. Not a cookie, but functions similarly for data persistence.
4. Advertising

IndexBody participates in the Google AdSense advertising programme. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising by visiting Google Ad Settings.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.

6. Your Rights

You have the right to access, correct, or delete any personal information we hold about you. Since we store minimal data, the primary actions available to you are clearing your browser's localStorage (for saved calculator results) and opting out of Google Analytics and AdSense cookies.

For GDPR or CCPA-related inquiries, contact us via our contact page.

7. Children's Privacy

IndexBody is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information, please contact us and we will delete it.

8. Changes to This Policy

We may update this privacy policy from time to time. The date at the top of this page reflects the most recent update. Continued use of IndexBody after changes constitutes acceptance of the updated policy.
